... Is the long-term expected per capita growth rate (r) of a population simply an average across years? Consider this hypothetical example: rgood = 0.5; rbad = -0.5 If the numbers of good & bad years are equal is the following true? rexpected = [rgood + rbad] / 2 At t0, N0=100 t1 is a bad year, so N1 = ...
